Abstract (en)
[origin: EP0703511A2] An image-forming machine comprising a rotary drum (10) and a cleaning means (12) which removes toner remaining on the peripheral surface of the rotary drum. The cleaning means (12) includes a support member (28) that extends in a direction parallel to the center axis of the rotary drum, a blade-holding member (44) that is mounted on the upper surface of the support member (28) and extends parallel to the direction of said center axis of the rotary drum, and a cleaning blade (68) that is held by the blade-holding means (44) and also extends in a direction parallel to said center axis of the rotary drum. The blade-holding member (44) is allowed to swing on a swing axis which extends in a plane which is substantially perpendicular to said center axis of the rotary drum. An acute angle alpha is defined between the cleaning blade (68) and a tangential line to the drum at the location where the front end of the cleaning blade comes into contact with the peripheral surface of the rotary drum. Restriction members (94a,94b) are attached to the support member at both ends thereof, the restriction members having restriction portions (100a,100b) which are opposed, while maintaining a very small gap (x), to the upper surface of the blade-holding member (44) in order to restrict displacement of both ends of the blade-holding member (44) in a direction to separate them away from the upper surface of the support member (28). <IMAGE>
